What are they saying about 3D Printing?
• “next great technological disruption” – Economist Jan. 2013
• “new workers are mastering 3D printing, a technology that has the potential to revolutionize the way we make almost everything.” – President Obama, State of the Union Address, Jan. 2013

What is 3D Printing?
• “Additive manufacturing” where you create a 3D object one layer at a time
• Requires a 3D design created by tool such as auto-CAD
• Requires material such as plastic that can be melted then put on one layer at a time
• Moving build platform that draws each layer of a 3D design

3D Printing
• If you can imagine it, you can build it• 3D printing lowers cost and eases access to
manufacturing• Reduces the cost of and decreases the time
needed for an innovation cycle• Prototype – revise – prototype – revise: this
takes days rather than years
17
Innovation
• Inventors imagine shapes, products, tools• 3D printing gives inventors rapid prototyping
and modeling• Revisions and improvements can be added at
a fraction of the cost of “traditional” methods• “DIY” – ability to innovate, design, and
manufacture has never been easier
18
Your takeaway
• Why study technology? Driver of innovation and opportunity.
• Why study in a school of computing? Technology is what we do. At Seidenberg, we do cool things with technology every day.
